RE: Plants fizz and bubble alot
Most tap water tends to be high in Co2, and the alkaline hardness hasn't had a chance to degrade. If you witness "Pearling" predominantly after a water change then chances are you need more Co2 added to the system. Your plants obviously can metabolize more than you have present in the system the rest of the time. This is a neat indicator to give you a bit of insight into the Co2 chemistry of your own system ! Savvy ?
FTR 10 ppm phosphate is not necessarily high ? If you increase the Co2 your plants may make better use of the available nutrients, and lower that a bit ...
Some municipal water treatment experiences an increase in biological activity in periods of temperature tansition (Fall, and Spring fer instance). They usually compensate for this with added chemical treatment. In order to effectively remove those chemicals at the end of the process they may utilize Alum to mechanically filter out those additives. Alum causes many chemicals to congeal like chicken fat. Unfortunately it also causes blood vessels to constrict. Small blood vessels such as you might find in fish or your BRAIN !

may constrict to the point of bursting under blood pressure. Fish suffer massive coronarys. People suffer a high occurence of Strokes, and brain damage in infants (Cerebral Palsy).

For a superior species we don't always grasp the big picture ???

Russ, doing weekly 50% changes now for three months.
Professor Myers, Cyano Bacteria I do not see it only green spot.
I retested the water all the same but there are High phosphate levels at 10 ppm will that make it toxic?
When I do the water changes the plants fizz and bubble alot after can you all tell me what that means?
Do you all know of any things else that will be in the water that will make it toxic and what not to add with EXCEL that makes the water toxic so I know?
